Three negative point charges q1 =-5 nc, q2 = -2 nc and q3 = -5 nc lie along a vertical line. the charge q2 lies exactly between charge q1 and q3 which are 16 cm apart. find the magnitude and direction of the electric field this combination of charges produces at a point p at a distance of 6 cm from the q2

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.
